from the Nemo Kernel config :
# CONFIG_PREEMPT_NONE is not set
# CONFIG_PREEMPT_VOLUNTARY is not set
CONFIG_PREEMPT=y
According to the kernel bug report, the problem can be avoided by compiling the kernel with CONFIG_PREEMPT_NONE set (and of course the CONFIG_PREEMP not set).

I'm not sure what side effects that has. Need to do some more digging for that...

UPDATE : I see why this option was chosen, to reduce latency.

Might be a proper kernel patch solution is the best one, if existing ... I'll dig up the link for the Nemo/Mer bug report.
